The Commodore 64 (1982), almost certainly the best-selling computer model
of all time. Ex-Commodorian Andy Finkel estimates that sales totaled
between 17 and 22 million units. That's more than all the Macs put
together, and it dwarfs IBM's top-selling systems, the PC and the AT. Commodore
made significant technological contributions as well. The 64 was the first
computer with a synthesizer chip (the Sound Interface Device, designed
by Bob Yannes). The SX-64 (1983) was the first color portable, and the
Plus/4 (1984) had integrated software in ROM.

A computer that is both hardware and software compatible with the immensely
popular Commodore 64. Capable of running hundreds of popular CP/M business
titles using a built in Z-80 processor. A true upgrade over its predecessors,
sporting 128k of memory, RGBI monitor compatibility for sharp video
output, a keyboard to rival that of their business computers, and a
significant upgrade to their built-in BASIC interpreter and operating
system.
